Excluding allure-labels in pytest run

#### I'm submitting a ...
- [ ] feature request

#### What is the current behavior?
We have CLI param `--allure-label` and its possible to INCLUDE labels. Like `--allure-label method=AnyMethod` and it works

#### If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
But I decided to try to exclude from run tests with `@allure.manual(True)` decorator and came across a bunch of things:
1. You can't even include by label if your value (but it's default value) is a bool type. Example: if you set `--allure-label ALLURE_MANUAL=True` in CLI so it will deselect everything.
2. But I could find an interesting moment: if to write decorator like `@allure.manual('True')` and set the same `--allure-label ALLURE_MANUAL=True` in CLI -- it works and manual tests will be selected.

#### What is the expected behavior?
I want not just include labels, but also exclude. Something like `--allure-label "not ALLURE_MANUAL=True"`

#### What is the motivation / use case for changing the behavior?
We write tests as code and we dont need manual test cases in allure report. With this feature we will be able to run night tests and they will be closed automatically in allure testOps.

#### Please tell us about your environment:

- Allure version: 4.22.1
- Test framework: pytest==7.2.2
- Allure adaptor: allure-pytest==2.13.2

Empieza por rastrear cómo el adaptador de pytest analiza el parámetro CLI --allure-label y lo compara con los valores del decorador allure.manual. Comprueba el comportamiento de inclusión existente y determina cómo debería representarse una expresión de exclusión como "not ALLURE_MANUAL=True". Se considera terminado cuando las etiquetas con valores booleanos funcionan de forma coherente y las etiquetas coincidentes pueden excluirse de la ejecución.
